kelure

noun. fountain

A noun in the Quenya Verbal System of the 1940s glossed “fountain”, derived from the verb ᴹQ. kelu- “spring forth (of water)” and a suffix of general action: ᴹQ. -re (PE22/110).

Conceptual Development: A possible precursor is (archaic) ᴱQ. †kektele “fountain” from the Qenya Lexicon of the 1910s, a combination of the roots ᴱ√KEKE “bubble up” and ᴱ√KELE “flow” (QL/46), also mentioned in the Poetic and Mythological Words of Eldarissa (PME/46).
